In situ generated confined single-atom Co 3+ sites with a low coordination number and abundant oxygen vacancies demonstrate enhanced stability activity for acidic evolution broken scaling relations.
Abstract The stability of Pt‐based catalysts for oxygen reduction reaction (ORR) in hydrogen fuel cells is seriously handicapped by the corrosion their carbon supports at high potentials and acidic environments. Herein, a novel SnS 2 /SnO hetero‐structured support reported Pt nanoparticles (NPs) as ORR catalyst, where NPs are mainly deposited interfaces SnO moieties. Pt‐support interactions, which can be tuned concentration heterointerfaces, accelerate electronic transfer enrich electron...
The complex chemical environments and strictly limited mass transport in the catalytic layer (CL) of proton exchange membrane fuel cells (PEMFCs) seriously hinder their performance. In this study, a one-dimensional atomically dispersed Co–N4/C porous carbon nanofiber (Co–N–PCNF) supported intermetallic L10-PtCo nanoparticle is developed as an advanced PEMFC cathode via electrospinning. Thanks to suitable pore structure homogeneous ionomer distribution, unique CL exhibits excellent...

Abstract Metallene is considered as an emerging family of electrocatalysts due to its atomically layered structure and unique surface stress. Here we propose a strategy modulate the Bader charge transfer (BCT) between Pd oxygenated intermediates via p ‐ d electronic interaction by introducing single‐atom ‐block metal (M=In, Sn, Pb, Bi) into metallene nanosheets towards efficient oxygen reduction reaction (ORR). X‐ray absorption photoelectron spectroscopy suggests that doping metals could...

For crystals, depressed cladding waveguides have advantages such as preservation of the spectroscopic well non-linear properties and capability to guide both horizontal vertical polarization modes, but fabrication is always quite time consuming. In addition, it usually difficult couple modes propagating in different through evanescent field overlap, so often required dynamically reconfigure photonic waveguide devices using external fields for classical or quantum applications. Here, we...
